Internal compiler error

When I do a "build all" of my Delphi3.02 project, it compiles all units, except 2, and gives a fatal error "Internal Error L1086". This occurs with both IDE and command line compiling.
I cannot trace what I changed in the code since last succesful "build all".
Deleting all .dcu files, and doing a build all (which doesn't generate the .exe, due to this error above) followed by a normal "compile" generates the .exe and it seems to be OK, but, for example, the version isn't auto-incremented, etc.

Does anybody have any experiences with internal compiler errors, does there exist explanations ?

This error seems to come every time a lot of units has been compiled. It's a linker error. Just do a Compile after the error and everything is Ok.
This error is gone in D4, now it's L 511 :-) (And I'm not kidding!)

this error has been described to occur because of lines like
  TInternalError = type TObject;
it is a compiler error that fixed or known.
If you don't update to D4 trace the error to the unit by commeting out part by part.

Thank you for your answer. It wasn't really the "solution" for my problem, but I must admit that my actual question (last sentence)  doesn't cover my problem... So you did answer my question...

Nonetheless, your answer assured me that it was not my fault and I began to search: I moved all .pas files to another directory and one after another, copied them back, each time doing a build all.  Like that I found the unit which caused this compiler error.

In the end it was the third string in a "resourcestring" section:
----Before: (doesn't work)---
resourcestring
S_WantOverwrite= '%s already exists.'+#13#10
                +'Do you want to overwrite it ?';
S_WantSkip='Do want to skip all following existing files ?';
NoAssignmentName='(no assignment)';

----After: (does for build all)---
resourcestring
S_WantOverwrite=...
S_WantSkip=...
const
NoAssignmentName='(no assignment)';

I don't have the time to explore this, and at the moment it doesn't matter whether it's resourcestring or not.

Hmmm. I hope you reported your findings to Inprise,
so that at least the work was of some use.
I once was lucky(?) to report a previously unknown
small "issue" to interbase and yes I got a mail back
asking for a test case.
